Almost everyone needs help with their content marketing—it’s a battle royale for audience attention, and even if you’re a content powerhouse like Red Bull it still takes an incredible amount of work to stay on top. And if you’re just getting started, you need to come out swinging with high-quality stories from the beginning.

But while it’s easy to know that you need help, it’s harder to know who to turn to. Since content marketing is such a new discipline, not everyone knows what to ask for. Over the years many of the world’s biggest companies have asked us to create a set of questions to evaluate potential vendors—in other words, a content marketing RFP (Request for Proposal). Contently VP of Marketing Ray Cheng shed light on those questions earlier this year, and the topic was so popular that we had our friends at Ceros create an interactive guide to the 10 questions you should ask your next content marketing vendor.

Click around in the guide below to dive deep into the questions you should ask—and why you should ask them–and for the full, interactive experience, head here.

Enjoy, and if you want a downloadable PDF of these questions that you can send to the content marketing vendors you’re considering, see the link below the piece.
